摘　　要：区分服务为不同数据流提供了不同方式和级别的服务,可以为重要性不同的应用提供不同的带宽和优先级保证。Linux平台具备功能强大的带宽管理工具集,为应用的分类和带宽保证提供有效手段。通过结合区分服务规范定义的加速转发、保证转发,以及传统尽力而为的转发方式,在Linux平台上使用流量控制工具集TC,设计并实现了不同类数据流的区分和带宽保证,建立了区分服务逐跳行为在Linux下的映射模型。Since diffserv architecture provides differentiated services for different types of data-flow, special bandwidth for more important applications is allocated and their priority is ensured. Linux supports us with functional bandwidth-management tool sets, which make it feasible to classify our applications and give assurance to their bandwidth accordingly. Correlating the expedited forwarding, assured forwarding defined by diffserv workgroup with the conventional best-effort service, the diffserv＇s per-hop behaviors is designed and implemented by using traffic control tool-set TC under Linux environment.
